The reaction mixture was allowed to warm at room temperature and was stirred for 20 h. The precipitate of pyrazolotriazinone or imidazotriazinone was then filtered off, and the residue was diluted with water (20 mL), extracted with dichloromethane (3 \u00d7 30 mL), and dried with anhydrous MgSO4. The resulting solution was concentrated to dryness, and the solid was then subject to chromatographic column separation with dichloromethane and dichloromethane\/ethyl acetate in different proportions.<\/p>\n<p>The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking.
